Instead of booking car hire, why not make one of the LHR-SOF trips an overnight or extended stay and book a hotel - with BA Holidays you can book a hotel for just one night rather than the whole duration; overnighting/few hours in SOF gives you some slack for delays etc and you'd get double tier points which might remove the need for so many trips

Have you though about booking 5 days care hire at SOF for some of these runs? I think it should be fairly cheap. Thereby making them valid for the double TP offer. (I believe you don't need to actually ever pick up or go near the car hire place).
e.g. if you book car hire at SOF for booking A you'd get 160 TPs in total.
